KBIA also broadcasts three HD Radio services: KBIA2, which airs classical music when the main KBIA signal airs news, and vice versa; and KBIA3, which airs an AAA format.

In November 2014, KBIA announced it was buying KWWC-FM (90.5) from neighboring Stephens College. Once the sale is completed, the Classical Music format heard weekdays on KBIA will move to 90.5, while KBIA will transition into a news/talk/information station similar to sister stations KCUR Kansas City and KWMU St. Louis.

KBIA also operates translators KKTR 89.7 in Kirksville, and KAUD 90.5 in Mexico.
